COMBINED SASH LIFT AND WINDOW LOCK.

Application filed April 23, 1923. Serial No. csassr/ To all whom it may concern:

Be it known that I, GEORGE It. Hal-I, a citizen of the United States, residing at Dayton Township, in the county of Newaygo and State of Michigan, have invented a new and useful Improvement in a (30mbined Sash Lift and Window Look, of which the following is a specification.

The object of this invention to form a single operating unit that shall. serve the double purpose of a sash lift for raising and lowering the window and a locking belt for locking the window securely when it is closed down, and holding it in position when raised. I attain this object in the manner shown by the accompanying drawing in which Fig. 1, shows the lock in position when the window is closed down and securely locked;

Fig. 2, shows the lock in position when the window is raised and held in position;

Fig. 8, shows the lock in position to pass the stops when in use as a sash-lift Similar numerals refer to similar parts throughout the several views.

This article may be cast, but I prefer to form it from a piece of sheet metal of suitable size and temper by bending two por tions thereof at right angle to each other; one portion is trimmed to suitable size and shape to form a convenient and effective handheld 1, for use as a sash-lift in raising and lowering the window; the other portion forms a base 2, for attaching to the face of the sash bar. Upon this base two extensions 4l-.-7 and 56, are formed and shaped to form locking bolts.

Integral formation as a part of the base is preferred for these extension; but they may be separately formed and rigidly secured to the base in such manner that the base 2-, the hand-hold 1, and the locking bolt extensions l;-7 and 5-(i, shall form a single oi ierating unit which is pivotally mounted upon the face of the sash bar by the screw 3, in a manner to permit a slight rotary or rocking motion sufficient to operate the locle ing bolts il 7 and 5-43, by causing them to engage suitable projecting stops placed on the window casing.

The extension 47, extends from the base 2, toward the window casing with an upward angle which disposes its terminal end 7, above the pivotal screw 3; it is shaped to form a locking bolt by bending its ter minal end 7, forward at right angle to 4 thus forming a narrow locking face adapted to engage the special stop 8, and lock the sash down securely when the window is closed. For holding the sash in position when raised a series of regular stops (of which 9, is one) is placed onthe casing abovethe special stop 8, and at a distance from the face of the sash exceeding the width of the locking'face 7, this permits the locking bolt 47, in any po'sition to pass freely up and down without contact with any stop except its own special stop 8, when down and in looking position Extension 5-6, extends from the base toward the window casing with a downward angle which disposes its'terminal end 6, below the pivotal screw 3; it is shaped to form a locking bolt in sameinanner as 4.--7, except that its terminal end 6, which is bent forward at right angle to 5, is longer and forms a broader locking face having sulii cient width to engage the series of regular stops (of which 9, is one) and hold the window in place when raised.

The motion of the operating unit formed by the base 2, the hand-hole 1, and the looking bolts l7 and 56, is limited by the stop 13, in the slot 10; length of slot controls length of motion. The slot 10, and stop 13, are placed in such relation to the pivotal screw 3, that the extreme limit of motion toward the window casing ill place the hand-hold 1, approximately level and in its most convenient and efiective position for use as a sash-lift in raising and lowering the window. In this position (Fig. the inching bolts will pass all regular stops without contact, but the extreme reverse motion will engage any one of the series of regular stops and hold the window in posi tion when raised.

All stops project sufliciently to permit locking bolts to engage them without contact with the surface to which the stops are secured. The pivotal screw 3, ant stop 13 are placed at such distance from the window casing that the extreme limit of motion in any direction does not permit the locking bolts to come in contu't with tie surface to which the stops are secured.

I claim; 7

1. In a combined sash-lift and windowlock, thecombination of a hand-hold of suitable size and shape for convenient and effective use as a sash-lift, a pivotal base, a narrow-faced locking bolt adapted to en gage a special stop to lock the window down, a broad-faced looking bolt adapted to engage a series of regular stops to look the window in"positionwhen raised all shaped and united to form a single operating unit pivotally mounted upon the face of the'sashbar in combination with a limiting stop limiting its motion whereby itisadapted-and made toserve the double purpose of a sashlift and locking bolt.

2. In a combined sash-lift and windowlook, the combination of a hand-hold of suitable size'and'shape for convenient and effective use as a sash-lift, a pivotal base, a narrow-facedlooking bolt adapted to engage a speeial'stop to lock the window down, a broad-faced looking bolt adapted to engage a series of regular stops'rtolo'ck the window in position when raised;- all shaped and united to form a single operating unit pivot-ally mounted upon the fare of the sashbar 1n combination with a limiting stop limiting its motion, a special stop secured to the window casing near to the face of the sash-bar and-adapted to engage the narrowfaeed looking bolt to look the window down anda series of'regular stops secured to the window casing farther away from the face of the sash-bar and adapted to engage the broad-faeedloeking bolt'to hold the window in position when raised, whereby the combilift and a window-look.
